PIIINEAS F. KING, OF CINCINNATI, OHIO, ASSIGNOR TO THE MOSLER BANK SAFE COMPANY, OF SAME PLACE.

SAFE-FRO NT.

SPECIFICATION forming part of Letters Patent No. 451,695, dated May 5,1891.

Application filed July 28, 1890. Serial No. 360,160. (No model.)

To all whom it may concern.-

Be it known that I, PHINEAS F. KING, of Cincinnati, Hamilton county, Ohio, have invented certain new and useful Improvements in Safe-Fronts, (Case 0,) of which the following is a specification.

This invention pertains to burglar-proof safes of that type known as circular-door safes, and relates to improvement designed to add to the resistance offered by the front angles of the safe.

My improvements will be readily understood from the following description, taken in connection with the accompanying drawings, in Which- Figure 1 is, a perspective view of a safefront illustrating my improvement; and Fig. 2, a plan and half-horizontal section of the front of a safe constructed in accordance with my invention.

In the drawings, Aindicates the front face of a circular-door safe; -13, the backing-plates secured in series against the interior of the front face of the safe and having circular openings concentric with the opening in the front plate; C, the margin of the front, arranged in the form of a rectangular frame of angle-bars, one face of these angle-bars JOllling the side walls of the safe, while the front faces of the angle-bars form the facial margin of the front of the safe; D, the spandrel braces of the front integral with the facial angles of the angle-bars and giving to the front of the angle the form of a rectangle with a circular opening in it; E, the circular opening in the front, this opening being integrally margined by the front of the anglebars and by the spandrels; F, the opening in the backing-plates within the angle-front to the rear of the opening E, these openings altogether forming the stepped jamb for the circular door; G, the usual nut for a screwdoor when a screw-door is employed, secured within the safe to the rear of the backingplates F.

The front face A, with its circular opening and integrally-formed spandrels and angles,

presents the maximum area at its rear for the direct and solid attachment of the backingplates, and the spandrels form braces extending quite from the vertical to the horizontal centers of the opening, the angle-bars being thus free from parallel portions capable of side bending away from the opening. Here tofore the angle-bars of circular-door safes have been formed into integral rectangular frames by re-enforced and welded corners, but straight unbraced portions of the anglebars were present at the four sides of the circular-door opening.

In producing this improved front by one method the angle-bars are first Welded up at the corners. Then the spandrels are welded in. Then the door opening is accurately bored. Then the backing-plates are properly secured within the angle-front, so as to become firmiyunited thereto. The front edges of the safe-walls will preferably have a frontal rabbet to receive the side edges of the anglebars and form a flush surface outside. The nut, if used, is then secured to the back of the angle-front and the door is fitted to place, as usual. The front is then applied and secured to the safe-body by usual or proper means. By another method the welding is dispensed with and the front is formed by fianging a fiat plate and then boring the circular opening.

I claim as my invention In a burglar-proof safe, the combination, substantially as set forth, of a rectangular angle-frame having a front plate integrally formed With it and provided with a circular opening margined by integral spandrel-braces extending from the vertical to the horizontal centers of the angle-frame, and backing-plates disposed against the inner faces of the spandrel-braces and provided with circular openings concentric with the circular opening in the front plate.
